Red margin on C. Parva leaf

A new leaf on one of my cryptocoryne parvas has developed a red margin around the outside of the leaf.
It is in a fairly new setup (~a month old), with new Amazonia and EI dosing so I wouldn’t have thought it was a deficiency of nutrients. I have been dialling in CO2 over the last week so I suspect inconsistent co2 is probably the cause, but wanted to check to see if it could be anything else in case it was a sign of further issues ahead.
